ONE FERTILTY 2010-2012 vs CARTR 2011 compared success rates chart    

What is the difference between Beta hCG and Clinical Pregnancy Status?

The earliest sign of a pregnancy is the beta hCG hormone, which can be found in blood work twelve to fourteen days after ovulation.  Clinical pregnancy is diagnosed when a fetal heart beat can be seen on ultrasound, usually around six to eight weeks from the last menstrual period (four to six weeks after ovulation).

What is CARTR?

Since 2001, under the leadership of the Canadian Fertility and Andrology Society and the IVF Medical Directors of Canada, all in vitro fertilization (IVF) centres in Canada have voluntarily participated in the collection of nationwide data on the results of IVF treatment cycles (including intracytoplasmic sperm injection
[ISCI] cycles). This data is tabulated in the
Canadian Assisted Reproductive Therapies Register (CARTR), and reported annually, by clinic and by nationwide averages (see
www.cfas.ca for further details).  In the most recent report, the CFAS confirmed that the rates of pregnancy and live birth in the country's fertility clinics are on par with other national registries, including the United States. The complication rates remain low.

Starting in January 2013, CARTR will be merging with Better Outcomes Registry & Network (BORN) Ontario, the Ontario perinatal registry. This collaboration will enable improvements in CARTR data collection, analysis, and reporting.  In addition, for infants born in Ontario, it will allow more detailed and extended follow-up of the health of mothers and infants both before and after birth.
